ABCD is a rhombus. Find m

angle ABD=28 degrees

Step-by-step explanation:

Diagonals of a rhombus are perpendicular so all angles at point E are 90 degrees.

Diagonals of a rhombus also bisect the corner angles.

therefore:

angle CBD=ABD

angle CBD=90-62=28 degrees

so angle ABD=28 degrees

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
